We review the properties of neutron matter in low-density regime. In particular, we revise its ground state energy and superfluid pairing gap analyze their evolution from weak to strong coupling The calculations are performed, respectively, within Brueckner–Hartree–Fock (BHF) approach nuclear Bardeen–Cooper–Schrieffer (BCS) theory using chiral nucleon-nucleon interaction Entem Machleidt at N 3 ...
